After a tenant is added, you are advised to authorize the project or resource set of the tenant to a specified data protection administrator for further data protection operations.</p>
<div class="section"><h4 class="sectiontitle">Context</h4><p>The system administrator of the <span>OceanProtect</span> has the permission to perform operations on all resources. You are advised to authorize a specified data protection administrator to manage resources by project or resource set.</p>
